Why This Wattage?
Power Calculation
The recommended PSU wattage is calculated based on the total power draw of your CPU (Intel Core i7-13700K) and GPU (NVIDIA GeForce RTX 5080), plus approximately 100W for other components like motherboard, memory, and storage devices.
Extra Headroom
We add an additional 30% headroom to ensure optimal efficiency, handle power spikes, and allow for future upgrades. This ensures your system runs stable and your PSU operates in its optimal efficiency range.
Efficiency Standards
We recommend power supplies with 80 Plus certification, which represents higher energy efficiency and more reliable performance. Power supplies are most efficient at 50-60% load, so having adequate headroom is important.
Power Efficiency Tips
Enable Intel Speed Shift and SpeedStep in BIOS to dynamically adjust CPU frequency based on workload, saving power when idle.
Utilize NVIDIA's GeForce Experience software to optimize game settings for both performance and power efficiency.
Consider undervolting the GPU slightly to reduce power consumption without significantly impacting performance. This can be done with MSI Afterburner.
Special Installation Note
Ensure the 12VHPWR (12V-2×6) cable is fully and securely connected to the RTX 5080. Double-check the connection to avoid any potential issues related to insufficient power delivery.
Usage Scenarios
Ultra Gaming
Play the latest AAA titles at maximum settings, 4K resolution, and high refresh rates with ray tracing enabled smoothly.
Content Creation
Effortlessly edit 4K videos, render complex 3D models, and stream high-quality content without performance bottlenecks.
AI Development
Train machine learning models, run complex simulations, and experiment with AI algorithms quickly and efficiently.
Installation Tips
Position Properly
Most cases have a dedicated PSU bay at the bottom. Ensure the PSU fan is facing down if your case has bottom ventilation, allowing it to draw cool air from outside.
Cable Management
With modular PSUs, connect only the cables you need. Route cables behind the motherboard tray when possible for better airflow and cleaner appearance.
Proper Connections
Ensure all power connectors are fully seated and locked. The NVIDIA GeForce RTX 5080 will require dedicated PCIe power connectors from the PSU.
Test Before Completing
Before fully closing your case, connect the essential components and test that your system boots correctly with the new power supply.
The Thermaltake GF1 850W Gold is perfect! It's fully modular and has plenty of headroom for your i7-13700K and RTX 5080.
